Tunable space-time crystal in room-temperature magnetodielectrics
Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova, Dmytro A. Bozhko +5
We report the experimental realization of a space-time crystal with tunable periodicity in time and space in the magnon Bose-Einstein Condensate (BEC), formed in a room-temperature…
Long-distance supercurrent transport in a room-temperature Bose-Einstein magnon condensate
Dmytro A. Bozhko, Alexander J. E. Kreil, Halyna Yu. Musiienko-Shmarova +4
The term supercurrent relates to a macroscopic dissipation-free collective motion of a quantum condensate and is commonly associated with such famous low-temperature phenomena as s…
Optical determination of the exchange stiffness constant in an iron garnet
Keita Matsumoto, Thomas Brächer, Philipp Pirro +7
Brillouin light scattering measurements were performed in the backscattering geometry on a Bi-substituted rare earth iron garnet. We observed two different peaks, one attributed to…
Backscattering immunity of dipole-exchange magnetostatic surface spin waves
M. Mohseni, R. Verba, T. Bracher +4
The existence of backscattering-immune spin-wave modes is demonstrated in magnetic thin films of nano-scale thickness. Our results reveal that chiral Magneto Static Surface Waves (…
From Kinetic Instability to Bose-Einstein Condensation and Magnon Supercurrents
Alexander J. E. Kreil, Dmytro A. Bozhko, Halyna Yu. Musiienko-Shmarova +4
Evolution of an overpopulated gas of magnons to a Bose-Einstein condensate and excitation of a magnon supercurrent, propelled by a phase gradient in the condensate wave function, c…
Spin Seebeck effect and ballistic transport of quasi-acoustic magnons in room-temperature yttrium iron garnet films
Timo Noack, Halyna Yu. Musiienko-Shmarova, Thomas Langner +9
We studied the transient behavior of the spin current generated by the longitudinal spin Seebeck effect (LSSE) in a set of platinum-coated yttrium iron garnet (YIG) films of differ…
